A fastener assembly for securely fastening a decorative panel in spaced relation to a support backing includes a base member adapted to be operatively mounted to the decorative panel, a carrier member, and a linking member operatively extending between the base member and the carrier member such that the base member is disposed spaced from the carrier member. A fastening medium is supported by the carrier member and adapted to operatively interconnect the carrier member to the support backing. The linking member operatively interconnects the base member and the carrier member in articulating fashion such that the base member is transversely moveable relative to the carrier member.

A roller bearing for rotatably supporting a rotating shaft of an internal combustion engine between a main body and a cap of the internal combustion engine. The roller bearing including: a plurality of rollers; a retainer which is cirumferentially splittable and supports the plurality of rollers; and an outer race which is cirumferentially splittable and forms a raceway surface for the plurality of rollers. The retainer is split into a plurality of retaining members. The outer race is split into a plurality of race plates. At least one of the race plates is provided with one of a projection and a cavity to be engaged with one of the main body and the cap to restrict a relative movement between the one of the race plates and the one of the cylinder head and the cap.

A connector element for a post and beam construction having load-bearing glass components consisting of load-bearing glass posts and load-bearing glass beams, the connector element including a first fitting fitted to a first load-bearing glass component; a second fitting fitted to a second load-bearing glass component; and a glass load-transmitting element located between the first fitting and the second fitting.

A cradle bearing comprises a circular arcuate outer race arranged in a circular arcuate recessed part provided in a housing, a plurality of rollers arranged along the inner circumferential surface of the outer race and supporting a swash plate swingably, and a retainer for retaining the interval between the rollers. An engagement member and the end face of the retainer in the circumferential direction are in face-to-face contact with each other.

A fastener assembly securely fastens a decorative panel in spaced relation to a support backing. The fastener assembly includes a base member adapted to be operatively mounted to the decorative panel, a carrier member, and a fastening medium supported by the carrier member and adapted to operatively interconnect the carrier member to the support backing. At least one biasing member is adapted to operatively support the carrier member and provide swiveling articulation of the carrier member relative to the base member. At least one leg extends from the base member and is adapted to operatively engage the carrier member so as to attach the carrier member to the base member in articulating fashion.

The present invention provides improved retention of O-rings and easier O-ring replacement by using an O-ring retainer in a bar gun. Furthermore, the assembly of the butterfly plates of the bar gun is improved by using molded ball bearing clusters that fit in recesses in the butterfly plates, thus eliminating the welding of the balls to the butterfly plates and the need to purchase such precise and intricately small balls. The O-ring retainer and molded ball bearing cluster are preferably made from bearing quality acetal plastic materials.

A flexure based linear bearing includes top and bottom parallel rigid plates; first and second flexures connecting the top and bottom plates and constraining exactly four degrees of freedom of relative motion of the plates, the four degrees of freedom being X and Y axis translation and rotation about the X and Y axes; and a strut connecting the top and bottom plates and further constraining exactly one degree of freedom of the plates, the one degree of freedom being one of Z axis translation and rotation about the Z axis.

A rocking bearing outer ring (12) includes an arcuate track member (13) having a track surface on its inner diameter surface, and a flange portion (14) projecting radially inward from each widthwise end portion of the track member (13). In addition, when it is assumed that L1 represents a circumferential length of the track member (13) and L2 represents a circumferential length of the flange portion (14), 0.2≦L2 / L1≦8 is satisfied.

A surgical apparatus having sufficient rigidity in a fixed mode and being freely operable in a steering mode includes one or more arm modules having at least one degree of freedom, each arm module including at least one steering cable to steer the arm module and a plurality of link units to form the at least one arm module, each link unit including a head disposed at an upper portion thereof and having a hemispherical shape, a seat formed at a lower portion thereof, and a sliding ball arranged at the seat, wherein the link units are arranged such that the head of one of the link units is seated on the seat of the other of the link units, and the head of one of the link units and the seat of the other of the link units are slid with respect to each other by the sliding ball.

A shaft assembly having a first shaft and a second shaft interconnected by a bipot joint is disclosed. The first shaft and the second shaft are disposed in overlapping spaced relationship. The bipot joint includes a pivot block sandwiched between the first shaft and the second shaft. The pivot defines a mounting surface abutting one of the first and second shafts, and a semi-annular surface opposing the mounting surface and abutting the other of the first shaft and the second shaft. A fastener extends through a bore defined by the first shaft, the pivot block and the second shaft to interconnect the first shaft, the pivot block and the second shaft. The fastener includes a spring to bias the first shaft, the pivot block and the second shaft together, thereby de-lashing the bipot joint.

An apparatus for dispensing a beverage, for use with pressurized sources of one or more fluids, includes a handle having one or more valve chambers; a fluid valve in each valve chamber; one or more butterfly plates, each configured to bias one or more of the valve stems of the valves towards a valve-open position when the butterfly plate is pressed, thus opening fluidic communication from each of the fluid sources to a corresponding discharge opening; and a ball bearing cluster which provides one or more pivot points for the butterfly plates. The ball bearing cluster includes a retainer and at least one ball-shaped projection projecting from the retainer. The ball-shaped projection remains in a substantially fixed position and orientation with respect to both the retainer and the handle when one or more of the butterfly plates is pressed. The ball bearing cluster and butterfly plate may be molded.
